LBRICATOR.

To all whoml'it may concern.'

Be it known that I, BENJIMAN H. TURNAG'E, a citizen of the United States, residing at Blenheim, in the count-y of Marlboro and State of South Carolina,have invented ce1'- tain new and useful Improvements in Lubricators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to lubricators and has for its objecty to provide a simple and novel lubricating device for axle spindles upon which the wheels of the vehicle are mounted.

A further object of the invention is to provide means carried by the wheel and extending through the hub thereof for supplying lubricant to the axle, and means for regulatin the flow of the lubricant.

A rther object of the invention is to provide a lubricating device adapted to bel secured between the spokes of a vehicle wheel and having a valved sup )ly pipe extending through the hub thereol adapted to normally close the same, said device being i easily attachable or removable to or from the vehicle wheel.

With these and other objects in view, the

tion of my improved lubricating tevice thereof; Fig. 2 is an enlarged vertical section of the lubricator; and' Fig. 3 is a section taken on the line 3 3 of Fig. 1.

,Referring in detail to the.. accompanying drawing H designates the hub of the vehicle wheel and S the spindle of the axle upon which the same is mounted. Spokes W radiate from thewheel hub andbetween any two adjacent spokes of the wheeliny improved lubricator is adapted to be mounted.

The lubricator comprises a reservoir 5 which is of elongated tapered form for arrangement between the wheel spokes. The lower end of this reservoir is formed with a cylindrical tubular portion 6 and to the upper end thereof at opposite sides of the same the attaching plates 7 are secured, said plates being apertured to receive screws, nails or other suitable fastening devices for Specification of Letters Patent.

Application led October 22, 1910. Serial No. 588,528. l

Patented June wheel. the top 5 of the reservoir centrally formed with a threaded annulus `8 upon which the tubular neck..9 is adapted to be threaded, the lower end of this neck hav*- ing a plate 9 formed therein and provided with a central opening to receive the upper 1 end of the plunger'rt'idl() which is vertically movable through the reservoir A leather Washer 11 is arranged within the annulus 8 and against the under side of the plate 9. to obviate the liability Iof the oil being forced upwardly around the plunger and into the sleeve 9. The upper end of the plunger rod 10 is threaded, as shown at 10, for engagement in an interiorly threaded 4boss 13 formed 'within the cap 12. This cap is movable upon the sleeve 9 and such 'movement may be limited as desired by threading the cap upon the upper end of the plunger rod 10 to a greater or less extent. In this manner the quantity ofv lubricant discharged upon' the depression of the plungerrod may be suitably regulated. The `lower end of the tubular port-ion 6 of the reservoir isI closed by a head plate 14 and iirthis tubular portion the plunger or piston head 15 is movable; A coil spring 16 isgarranged between the plunger 15 and the head plate 14 and normally forces said plunger upwardly. A supply pipe 17 is threaded into the plate 1.4 and its lower end disposed through an opening in the hub H. A pressure valve 18 of any pre.- ferred construction is arranged in the lower ed ofthe pipe 17 and normally closes the sameto prevent. a continuous discharge of the oil upon the axle spindle. In the operation of my improved lubricator, when it is desired to lubricate the spindle, the operator presses downwardly upon the cap 12. thereby forcing the plunger 15 downwardly in' the lower tubular end 6 of the reservoir. This plunger 15 is spaced slightly vfrom the walls of the tubular extension of the reservoir so thaty the oil or other lubricant may flow around the same into thel lower end of the tube G and beneath the plunger head. Thus when the plunger is depressed this oil is forced through the pipe 17 and the pressure of the same opens the valve 18 whereby thel attaching the device to the SPQkgS of the with oil through the upper end thereof by ".removin the cap 12, sleeve 9, and the washer 11, or, i desired, a separate supply opening may be provided inthe top of the reservoir. The device is extremely s1mple and may be arranged upon the vehicle Wheel with but fis claimed is:

1. In a ljubricator, the .combination of a i 1reservoir `having a reducedftubula-r' lower endl said reservoir also having an opening in its top and a threaded flange Asurrounding saidopening, aplunger rod movable in said 1reservoir having ahead onits lower end. disvposed 'n vthe reduced portion thereof, said rod ex ending through' the opening, a tubu# lar neck threaded .upon said flange having a plate integrally -formed in its lower end n engaging upon the upper .end of the flange and closmg said opening, a washer arranged on the -plunger rod, said plate having an opening' therein 'through which the redis movable, a cap having an interlor bossthreaded-'upon the upper end d f said plunger rod andftele'scopically engaging said tubular neck,"the lower en d of said cap being adapted to engage'the top of the reservoir and limit the downward movement of the plunger, a headiny thelower endof thereservoir,.an oil 'conducting pipethreaded in Having. thus described the invention what .'said head, and a coiled'spring disposed be.

tween said head and the plunger'head to normally project the plunger rod upwardly within the reservoir.

2. .In-a'lubricator, the combination of aI i reservoir havingafeed opening in its top and a threaded flange surr(),undimggf.fsaidY opening, a plunger rod movabldins'aid reservoir'and extending through the feed opening and above the flange, a tubularneck Vthreaded lupo'n said flange "ha-ving? a `plate Aintegrally `formed 'in its lower end disposed on the flange and' closingthe ,feed opening,

a washer arranged onthe-.plunger rod beneath said plate, the upper end 'offsaid' plungei` rod being'threaded, a captelescopically engaged upon said tubularneck and havinga threadedsoeket therein to engage the threads on the plunger 4rod whereby 'said cap may be adjusted, thelower end of said cap engaging -with the top of the reservoir to limit the downward movement of the plunger, a plunger head on the lower end of said rod?, said reservoir having :111 outlet for the lubricant, and a coiled spring disposed' between said outlet andthe plunger head-.to normally. project said plunger rod upwardly.

In testimony whereof I hereunto aiix my signature'in the-presence of two witnesses.
